6.2 Parameter description
SITRANS P500 with HART
96
Operating Instructions, 12/2014, A5E02344528-09
Purpose: Setting the start of scale value
Description: This parameter allows the start of scale value for the volume scaling to be
set. The value that is set for "2.1.2.1.2 Setting LRV" (Page 84) or "2.1.2.2.2
Set LRV with Pressure" (Page 85) is automatically assigned to this value.
The start of scale value is expressed in the units you selected under "2.1.7.1
Volume Unit" (Page 95).
"2.1.7.3 Volume URV"
Factory setting: 100 m
3
Adjustment range: Freely selectable numeric value
Purpose: Setting the full scale value
Description: This parameter allows the full scale value for the volume scaling to be set.
The value that is set for "2.1.2.1.3 Setting URV" (Page 84) or "2.1.2.2.3 Set
URV with Pressure" (Page 85) is automatically assigned to this value.
You can enter the end of scale value in the unit selected under "2.1.7.1
Volume Unit" (Page 95).
"2.1.7.4 Curve activation"
The description of this parameter and the following ones can be found under:
"1.1.9.4 Level Curve" (Page 78)
"2.1.7.66 Density Unit"
Factory setting: g/cm
3
Adjustment range: g/cm
3
, kg/m
3
, lb/Gal, lb/ft
3
, g/ml, kg/l, g/l, lb/in
3
, ug/l, ug/m
3
Purpose: Selection of the unit for the density parameter
Description: This parameter allows you to select the unit for the measured density value.
"2.1.7.67 Density"
Factory setting: 1 g/cm
3
Adjustment range: Freely selectable numeric value
Purpose: Setting the value for the density
Description: This parameter allows you to set the value for the density of the medium,
which is used for conversion between volume and mass.
Adjust the settings for the measurement range when you change the values
for density!
